Food Web Dynamics and Ecosystems
- Testing food web theories and trophic cascade hypotheses: What is
the relative importance of bottom-up and top-down control in governing
food web structure?
- Interplay between bottom-up and top-down processes: Will
simultaneous bottom-up and top-down forces counteract or augment each
other?
- Connections between vertical and horizontal linkages in food webs:
Will horizontal linkages facilitate the spread of perturbations from
vertical pathways throughout the web, or dilute the effects of
perturbations?
- Trophic downgrading and upgrading: How can trophic manipulations
alter primary productivity, nutrient cycling, and carbon storage?
- Interactions between food webs in different habitats: How may
external resources such as spatial subsidies and allochthonous inputs
induce trophic cascades in focal habitat?
